Specification of Letters Patent.

Patented Sept. 9, 1919.

Application filed September 29, 1916, Serial No. 122,847. Renewed June 26, 1919. Serial No. 307,014.

To all whom it may concern:

Be it known that I, BENJAMIN E. GETz, a citizen of the United States, a resident of Morton, in the county of Tazewell and State of Illinois, have invented new and useful Improvements in lVashing-Machines, of which the following is a specification.

This invention has reference to mechanisms for imparting a reciprocating and oscillating movement to elements of a machine.

The invention has for its object, to improve the actuating mechanism for a dasher shaft of a washingmachine, the dasher being adapted to be reciprocated and during such reciprocal movement, to-beoscillated.

The application of the invention is preferably shown applied to a washing machinehaving a dasher shaft carrying a vacuum head, and known as a vacuum washer.

In the drawings,

Figure 1 is a plan view of a washing machine showing my improvements applied thereto;

' Fig. 2 is an elevation, partly in section, the inclosure for the working parts of the mechanism being opened to disclose the actuating means for the dasher shaft;

Fig. 3 is an enlarged elevation showing more in detail, the actuating means for the dasher shaft, parts being in the same position as they are shown in Fig. 2;

Figs. 4 and 5, respectively, are details in plan and in elevation, showing the actuating means for the dasher shaft in one position;

Figs. 6 and 7, respectively, are views similar to Figs. 4 and 5 and show the dasher shaft having made a partial rotation, and

Figs. 8 and 9, respectively, are views similar to Figs. 4, 5, 6 and 7, except that the dasher shaft has completed its rotating movement and elevated its full stroke.

Like characters of reference denote corresponding parts throughout the figures.

A designates the tub portion of the washing machine supported upon a suitable platform, stave legs, or other suitable means, not shown. The tub is provided with the lid B forming a closure for the machine, the same being hinged at points 0 so as to be raised and lowered for the purpose of permitting 1 clothes or other material to be placed in the tub or taken therefrom.

Secured to the lid B is a casting 1 having the frame 2 and formed with the axially disposed spaced bearings 3 and 4:. Hinged at points to an ear or plate extension 7 of the frame 2 are closures 8 and 8 for the frame 2 in which may be inclosed the actuating mechanism for the dasher shaft.

In Flg. 1, the closure 8 is fastened in a closed position by the member 9 and the closure 8 is fastened in position by the clasp 10 which fastens over a rib 111011 the frame 2. Access to the mechanism for inspecting the dasher shaft is bad by releasing t e clasp 10 and swinging the closure 8 away from the frame as is shown inFig. 2, except in said figure, the closure 8 has been entirely remove 12 designates the dasher shaft having reciprocal and oscillatory movement in the bearing 5 of the frame 2 and also in the base plate of the casting 1, the latter being secured to the lid of the tuband on the lower end of said dasher shaft is connected a vacuum head 13.

-N 0 bearing is formed for the dasher shaft in the lid of the machine, but an opening sufficiently large is provided, as shown in Fig. 2, through which the dasher shaft is carried and has movement. p

. 1 1 desi nates a driving shaft; This shaft is journa led in the bearings 3 and 4, the inner end of the shaft passing into the frame 2 and haying fastened thereon, a crank 15. Althouglrthe outer end of the driving shaft 14 is broken away, it is understood that in practice, this shaft is connected by gearing or other means with mechanism adapted to be operated by power, either from an electric motor or gasolene engine, and said shaft may or may not be controlled by aclutch for operating the same from said power actuating mechanism. These last mentioned parts are well known in the art and it is therefore not necessary to show the same as they form no art in the present invention.

ecured to the dasher shaft 12 at a suitable point is a casting 16, said casting being secured to said shaft by being formed with a. tubular bearing or collar 17 through which the shaft 12 is passed, and by means of which it. is secured to the casting l6. Said casting is further provided with the collar or. sleeve 18 off-set from and at right angles to the collar 17 and said sleeve 18 is formed 01' is provided with the square opening 19 extending therethrough.

Having reciprocal movement through the sleeve 18 of the casting 16, is a square bar 20, to one end of which are secured by means of a bolt 20", oppositely disposed plates 21 which are off-set at 22 to form a hearing, or a housing in which and to which is pivotally connected a block 23 to form a flexible connection between the plates 21 and the crank 15 of the driving shaft 14:. T hisconnection is made by means of a short stem 24 secured in the 11 per end of the crank 15 and held in,

the bloc 23 by means of the cotter pin 25.

I I prefer to make the flexible connection between the block 23 and the plates 21 by roviding said block With trunnions 28 ournaled in suitable openings in the plates 21.

The operation of the machine is as follows: assuming that the parts are operatively connected in the manner shown particularly in Figs. 1 and 2 and power being applied to the driving shaft 1 1, said shaftl t will be rotated and in turn rotate the crank 15 connected thereto. The rotation of the crank through the stem 24 will oscillate the dasher shaft 12' and at the same time, recip rocate said shaft in its hearing. The block 23 forms a flexible connection to allow for the rotating movement of the crank 15 and. also permits the reciprocal movement of the squared bar 20 which has reciprocal move-- ment in the sleeve 18 of the casting 16. In

.Figs. 3 to 9, both inclusive, the operation resulting in the reciprocal and oscillating movement of the dasher shaft, is very plainly seen. a The mechanism for reciprocating and oscillating the 'dasher shaft is of the simplest character and yet, embodies all the strength necessary in the few parts used to stand the strain incident to the washing operation during the up and down movement of the dasher shaft and its oscillation when Washing clothes.

what I claim is 1. In a mechanism of the character described, in combination, a hinged member, a casting secured to said member and formed with a frame, hinged closures for the opposite sides of said frame, a dasher shaft passin through said frame and having a hearing therein, a driving shaft journaled in said. casting, a crank secured to the inner end of the driving shaft within the frame, a casting secured to the dasher shaft and formed with a sleeve disposed at right angles to the dasher shaft, and connections between the casting on the dasher shaft and said crank, said connections including a flexible element located adjacent the crank.

2. In a mechanism of the character described, in combination, a shaft ournaled in bearings and adapted tobe reciprocated and oscillated therein, a casting secured to said shaft and formed with a sleeve which is offset and at right angles to said shaft, said sleeve formed with a square opening therethrough, an operating shaft, a crank carried on one end of said operating shaft,.a square bar reciprocally carried in the squared opening of the sleeve on the first menti-ond shaft, plates secured to said square bar, and a flexible connection between said plates and said crank.

3. In amechanism of the character described, in combination, an operating shaft, a crank on one end of said shaft, a second shaft adapted to have reciprocal and oscillatory movement imparted thereto, a casting secured on said second shaft, said casting having a sleeve off-set from and at right angles to said second shaft, and formed with a squared opening therethrough, a square bar having sliding engagen'ient in the sleeve of the casting on said second shaft, oppositely disposed plates secured to said bar and formed with off-sets, a block pivotally connected between the off-sets of said plates, and means for connecting said block to said crank.
